Equestrian sport is the only Olympic discipline jointly completed by humans and animals. In competitions, mutual respect, trust, and tacit understanding between rider and horse are essential for achieving the best possible performance. Therefore, the correct use of equestrian equipment is closely related to both the rider’s safety and the quality of athletic performance.

Among the equipment frequently used in equestrian sports are spurs. But what exactly are spurs? Spurs are short, blunt devices or wheels attached to the heels of a rider’s boots, traditionally used to prompt the horse to move faster, or perform precisely. Spurs have long been a controversial tool in both competitive equestrianism and horseback riding culture, as improper use can easily injure the horse. However, when used correctly, spurs not only avoid harming the animal but can also have a positive and supportive effect.

With this in mind, I propose the design of a smart spur. By integrating a thin-film pressure sensor onto the tip of a traditional spur, the device can record both the intensity and frequency of spur use. The collected data can then be transmitted in real time via wireless connection to the coach’s mobile phone, enabling immediate feedback and helping riders correct improper habits. In this way, the spur can serve as an auxiliary tool that enhances communication between rider and horse, strengthens mutual trust, and ultimately helps the rider deliver a better competitive performance.
